Sharing Is Caring
Abby and Brittany possess remarkable physiological characteristics. They have two separate hearts, two pairs of lungs, and two spines connected to a shared pelvis. Additionally, they each have their esophagi and three kidneys. However, they share a single ribcage, one liver, a partially shared nervous system, and a fully shared circulatory system.
Notably, from the waist down, everything is shared, including the reproductive system, intestines, and bladder. Despite their physical connection, each twin can only feel sensations on their respective sides of the body.
